Once upon a time, governing the Facebook community was relatively simple, because users—mostly American college students—shared at least some cultural context for what was and wasn’t acceptable. But now Facebook’s 1.39 billion users span a range of ages, ethnicities, religions, gender identities, and nationalities, and Facebook’s ability to create a space that meets everyone’s definition of “safe” increasingly has been called into question.

Which is why today, Facebook updated its community guidelines, spelling out in unprecedented detail what constitutes unacceptable behavior. Yet the unwieldy specificity of the new guidelines only proves that Facebook’s policies and procedures surrounding user activity will never be a finished product. As the world’s largest social network, Facebook certainly can learn a lot from the past, but it can never fully anticipate the future.

Facebook Inc. will let advertisers know where a promotion was first viewed and when it led to a purchase by tracking users between their electronic devices, a tool that may reignite privacy concerns.

Marketers will be able to see the number of users that clicked on an ad, whether they used a smartphone, tablet or desktop computer, and which device was used to buy a product, Menlo Park, California-based Facebook said in a blog post today.

Facebook’s earnings beat projections for the 8th quarter straight with $2.91B in revenue and $0.42EPS in Q2 2014. The service is growing about twice as fast on mobile compared to its services as a whole. Facebook now has 1.07 billion mobile monthly users, and 654 million daily mobile users. That helped it bring in 62% of its ad revenue from mobile. In total, Facebook now has 1.32 billion monthly users and 829 million daily users, or 63% of users returning each day. It beat Wall Street’s estimates of $2.81 billion in revenue and $0.32 EPS.

Google has decided to reverse its long-standing policy requiring users to use their real names to make profiles on the service as of Tuesday, according to a post shared on the official account. The move comes after Google+ head Vic Gundotra suddenly departed in April, marking the beginning of a shift for the service.

A study of how older teenagers use social media has found that Facebook is “not just on the slide, it is basically dead and buried” and is being replaced by simpler social networks such as Twitter and Snapchat.

Young people now see the site as “uncool” and keep their profiles live purely to stay in touch with older relatives, among whom it remains popular.

Next time you host a soiree, you can collect photos of the event from your guests in one album on Facebook.

The social network has added shared photo albums so people can throw photos from an event or of a common subject into a single spot. The new shared album feature, first reported by Mashable, is rolling out to English-speaking users of the social network but will eventually be available around the world.
